The master's thesis examines the impact of active breaks on reducing the negative consequences
of prolonged sitting, which is increasingly prevalent in modern workplaces. The study highlights
the risks associated with a sedentary lifestyle, including musculoskeletal disorders,
cardiovascular diseases, metabolic disorders, and negative psychological effects. The aim of the
thesis was to assess the effects of active breaks on employees performing predominantly
sedentary work. The study involved 34 employees who participated in a one-month intervention,
performing active breaks every 60 minutes during working hours. The research was based on
questionnaires evaluating discomfort and pain levels in various body parts, changes in physical
activity, and mood before and after the intervention. The results showed a statistically significant
reduction in lower back pain (p = 0.02) and an increase in high-intensity physical activity (p =
0.036). While no statistically significant differences were observed in other indicators such as
overall mood, moderate physical activity, and sitting time, the trends suggested positive effects.
A particularly important finding was the negative correlation between walking and lower back
pain, indicating that more walking led to reduced discomfort in this area. The study also aimed to
determine whether active breaks influence employees' overall well-being. Although
improvements in mood were not statistically significant, participants reported reduced fatigue
and increased work efficiency. Additionally, they provided suggestions for enhancing the active
break program, such as incorporating more exercises targeting the upper body. The study
concludes that active breaks are a simple and effective strategy for reducing the negative effects
of prolonged sitting. Organizations are encouraged to implement structured breaks that include
stretching and activation exercises. Additional workplace adjustments, such as ergonomically
designed workstations and promoting walking, could further mitigate the health risks associated
with sedentary work.
